With Activision and Bungies recent wins against cheat providers it is time SE's

[HikariKurosawa]

No, they are not. People that scream for any sort of DRM/anti-cheat or whatever have no idea just how significant an impact implementing them would actually have. Putting aside the fairly substantial financial loss for a moment. The raid community would have virtually no way to vet potential recruits. Without ACT and FFlogs, you essentially have no resume of your past experiences. Even worse, you have zero way to parse information like, for example, if your group is hitting enrage, is it due to the DPS not dealing enough damage or the healers? On the whole, this would make recruitment an absolute nightmare, very likely causing harder content such as Ultimate to be entirely insolated. Basically, you'd need to know the right people or make a group yourself with no way of vetting your potential recruits on how they mitigate, healer and etic. Sufficient to say, that wouldn't go over well. PF would be in an even worse state where these same issues magnify.

All of the above could possibly lead to Ultimate being cut due to the potential clear rates dropping significantly. Nevermind, content like Criterion that already has immensely low participation rates and struggles mightily to attract interest. Keep in mind, in this hypothetical, cut content is inevitable because Square Enix certainly isn't going to eat the financial loss of players unsubbing. Ironically, this would lead to even more players unsubbing since the high end community would essentially have no content should Ultimate and Criterion get axed. Granted, there would be far bigger cuts considering neither of those take up a big produce of their budget according to Yoshida himself.

Of course, this is only the raid side of things. Once you factor in the RP community and how losing a substantial amount of both will effect other aspects of the game like content creators making guides, crafters who sell to both those demographics, raiders helping with PF, the sheer number of QoL plugins and etc. It highlights why SE is never going to do anything about third party beyond keeping it in a perpetual "grey zone" of "don't ask, don't tell." It's simply far too big a financial loss and will result in massive amounts of PR backlash with no actual benefit.

I'd argue that the whole "resume" part of fflogs and act is more offputting to a majority of players than it is encouraging them to engage with the content. Participation numbers would go up, not down. Not to mention, most parses are not an accurate representation of the player's skill or potential.

The amount of people who actually care about that stuff are an extreme minority.

Also what does it mean for ultimate content to become entirely insolated? Definitions of insolate. verb. expose to the rays of the sun or affect by exposure to the sun. “insolated paper may turn yellow and crumble”

The other thing is, PF ultimates are proof that all your claims are incorrect. You don't vet players in PF, they join the group, it fills, and you do the run. Tons of people clear the hardest content in the game through PF.
